COLLAR-FORMING nnan.

Specification of Letters Patent. P t nt g, 191

Application filed December 11, 1911. Serial No. 665,006.

To all whom it may concern:

Be it known that 1, JOHN J. SELTEN- REIGH, of Chioago,in the county of Cook, in the State of Illinois, have invented new and useful Improvements in Gollar-Forming Heads, of which the following, taken in connection with the accompanying drawings, isa, full, clear, andfexact description.

This invention relates to certain improvementsin collar ironing machines of the class set forth in the pending application of W. J. Quinn, #609,415, filed February 18, 1911 and the pending. application of W. Quinn, #627,500 filed May 16, 1911, and no claim is made herein to the invention or inventions disclosed in, either of the; above identified applications, and refers more particularly to the steam heated heads in which the edges ofthe collars are adapted to be pressed and smoothed in a manner somewhat similar to that set forth in Patent. No. 7 92,454 issued June 13, 1905 to W. J. Quinn.

The primary object is to provide means whereby the grooved portion of the head" into which the collar is adapted to be pressed may be heated more uniformly -on all sides of the groove. inner and upper sides as well as the outer sides. 1

Another object is to provide the sheet metal lining which fits snugly in the groove with simple means for retaining it in its op erative position. 7

Other objects and uses will be brought out in the following description:

In the drawings Figure 1 is a top-plan of a pair of collar forming heads embodying the features of my invention. Fig. E2v is-a front elevation, one-half in section, of the same pair of heads. Fig.3 is a perspective view of the detached sheet metal lining.

In carrying out the objects stated, I preferably employ a pair of hollow cast metal heads 1- of substantially the same circular form and size integrally united to each other side by side and adapted to be secured by any well known fastening means to a supporting frame for coaction with the collar supporting elements not shown but with which these heads are adapted to be used as shown in the patent referred to. These heads are provided with communicating steam chambers -2 having a common inlet 8 at their junctions one with the other, said heads being also provided with That is, at the annular grooves 4c in their undersides and between the inner andouter walls of the steam chambers 2, as best seen in Fig. 2, for receiving annular sheet metal linings 5] of different material such as copper, white metal] or similar material which, may be rolle'd or pressed to a smooth condition so as to takeon a high polish with an expenditure of a minimum amount of. 1311116 and labor. Each head is preferably provided with a central circular opening therethrou'gh concentric with its annular v groove ,-4-, one side of the openingbeing enlarged to form a radial recess intersecting the annular groove and communicating therewith so that the ends of the groove terminate at opposite sides of the recess to allow the tabs of the collars to enter said recess when the folded portionsthereof are pressed intothe groove. These sheet metal linings are ,V-shaped in cross s'ectionand the outer sides 6 thereof are of greater vertical depth than their inner sides 7. Each lining is tightly fitted in the corresponding groove 4 and a portion of the inner side thereof is cut awav at 8 to register with the corresponding recesses in the inner adjacent side of the head for receiving the flaps at the ends of the collar.

The outer wall of the groove 1 is provided with an inwardly projecting annular shoulder 10 located at a distance from the upper side of the groove 4: corresponding to the vertical depth ofthe adj acentside of the lining so as to hold said lining in place. That is, the lining is forced up into the groove 4 until its upper side engages the corresponding side of the groove, while the lower edges of the outer side of the lining which are somewhat yielding by reason of its being made of spring sheet metal, springs into place in engagement with the shoulder 10 after being slightly compressed during its insertion. The object in using this lining is to assure a perfectly smooth bearing for the edges of the collars throughout their entire upon a suitable form, not necessary to herein illustrate, and are pressed upv into the grooves of the linings 5 under considerable pressure suificientf to" smooth any rough edges which may appear on thepreviously ironed collar and byextending the steam chamber across and, t0 the inner and portions of the collars. hat I claim is:

1; A collar shaping head for collar ironing machines comprising V a ring-shaped 7 member having a circular groove in its under side and a; vertical open recess 1n its inner face extending radially to the annular groove for receiving the tabs of a collar,' a substantially circular sheet metal lining 'fitted in the groove and having a portion of its inner side cut away to form a I recess registering with the recess in the head,

and a shoulder on the head adapted to hold the lining in operative position. I

In Witness whereof I have hereunto set my hand on this 16th day of lg ovember,

1911. Y r a i r JOHN J. SELTENREIOH.
